xcms does not execute September 12, 2018, 03:19:37 AM I changed my computer and re-installed the whole packages, with the latest R version (3.5.1). Since then, xcms does not work anymore, remaining stacked at the first linexset<-xcmsSet(method="centWave", peakwidth=c(3,20), snthresh=5, mzdiff=0.01, ppm=3, prefilter=c(5,100000), noise=20000, integrate=1)xseta warning message indicate :Scanning files in directory C:/users/.... (blablabla until the correct file directory).. found 99 filesI also tried with the old R version that I installed and that used to work, but no success eitherI'm not a beginner with xcms, and I tried to process my files using another computer in the lab and everything is alright.I'm using windows 10 with an dell computer equipped with a Xeon processorany idea of what'sgoing wrong?many thanksjc Quote Selected
Re: xcms does not execute Reply #1 – October 24, 2018, 02:05:21 AM Eventually there is something strange going on with the parallel processing. Please add the following line right after you load the xcms package and retry:library(xcms)register(SerialParam())with that you disable parallel processing - if it runs without parallel processing we can think of a way to fix parallel processing.cheers, jo Quote Selected
